Output locking

You can implement output locking to produce video outputs that are frame accurate with each other. Implement output locking to enhance output redundancy, or to implement distributed encoding.

When outputs are locked together, they are frame accurate with each other. Frame accuracy means that two frames with the same timecode are identical in the following ways:

• The same content—the same picture on the video frame.

• The same segment number, manifest data, and so on.

• The same presentation timestamp (PTS).

There are two ways to implement:

• Standard output locking.

• Epoch locking.

Note

The information in this section assumes that you are familiar with the general steps for creating an event.
